This is a great place to stay in Bangkok.
Location is very good, Surasak BTS station is a few minutes away, and Sathorn Pier is a 10 minute walk. There was a place to eat on the corner, a great coffee near that, and convenience shops nearby.
Our room was very clean, comfortable, with a fan, A/C and an ensuite bathroom. We had a desk which was convenient as I needed to do some work. They have a washing machine with hot water in the house, which they charge a small amount for using.
Pong and Saya are wonderful hosts. They gave us lots of advice and were very nice people to talk to. Saya even helped make sure our Grab turned up at the right place when we checked out, and gave us a small gift.
This is one of the best places I've stayed at, and would recommend it to anyone visiting Bangkok.
